Answer: 20%
Step-by-step explanation:
To find the total number of problems Emilia solved, we can first add 19 and 76 to get:
19 + 76 = 95
Next, to find how many problems Emilia got correct out of the total, we can use the number of problems correct (19) and divide it by the total number of problems (95) to get:
19 ÷ 95 = 0.2
Finally, to make 0.2 a percentage, we can multiply it by 100 to get:
0.2 X 100 = 20
Therefore, Emilia got 20% of the problems correct.
When Peter does this, he is creating two sides of a right-angle triangle. The distance from his house to that point will be the hypotenuse of the triangle thus, to work out the length of the hypotenuse, we have to use Pythagoras Theorem! So:
a² + b² = c²
15² + 15² = c²
225 + 225 = c²
450 = c²
15√2 = c
21.21320344 = c
So, this rounded to the nearest tenth would be:
21.2 meters !
90 minutes or 1 hour and 30 minutes.

Answer:
After using the offer the carpet would cost Ahmed $180.
Step-by-step explanation:
Given:
Cost of the carpet = $240
Discount percent = 25%
We need to find the cost of the carpet after discount.
Solution:
First we will find the Discount cost.
Now we know that;
Discount cost is equal to Discount percent multiplied by Cost of the carpet divided by 100.
framing in equation form we get;
Discount cost = 
Now we will find the Cost of the carpet after discount.
Now we know that;
Cost of the carpet after discount is equal to Cost of the carpet minus Discount cost.
framing in equation form we get;
Cost of the carpet after discount = 
Hence After using the offer the carpet would cost Ahmed $180.
